PRACTICAL NUMERICAL PHOTOGRAPHY

This article contains results and comparisons in the field of numerical photogrammetry. It deals with three areas: orientation of models, aerial triangulation, and digitization. In the orientation area, relative orientation of incomplete models is discussed. A procedure of absolute orientation for the stereo model is developed, giving a close approximation of the stereo model base, the absolute longitudinal tilt, and the absolute lateral tilt to their final values. The required time for absolute orientation has been halved by using this procedure. In the aerial triangulation area, two large samples of strips and blocks have been adjusted and analyzed. The first contains 320 models of large-scale mapping, while the second contains 3800 models of small-scale mapping. The results of those adjusted strips and blocks were compared with other investigations. Also, a simple procedure for the use of the statoscope is shown. Independent model triangulation on the Wild A1o is the procedure adopted for aerial triangulation. An essential part in this type of aerial triangulation is the determination of the perspective center coordinates and their accuracy. This is given in a separate section. In the digitization area, a simple operational system is shown together with the mathematical transformations and computer programs used. /Author/
